The British company Reaction Engines Limited (REL) was awarded 1 million euros to develop an air breathing engine that could power the Skylon spaceplane.  The engine would run on hydrogen as the fuel and use liquid oxygen as a coolant instead.  It would also have a redesigned exhaust nozzle to get more force from the fuel which would increase it’s carrying capacity by 10% if it works.  One problem they have to sort out is to make sure that it doesn’t melt or deform the engines.  But overall this sounds like a great idea…I wonder why we haven’t tried coming up with this?
